ADDITIONAL OS VERSION INFORMATION :

EXTRA RELEVANT SYSTEM CONFIGURATION :
User name has a space in it.

A DESCRIPTION OF THE PROBLEM :
This line in the ./postinstall is incorrect and will fail if the username has a space in it:

${SU} - ${CONSOLE_USER} -c "${LSREGISTER} -f ${JWS_APP}"

I believe the correction should be:

${SU} - "${CONSOLE_USER}" -c "${LSREGISTER} -f ${JWS_APP}"


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create an OSX user with a space in name e.g. "my user" and attempt JDK installation

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JDK install succeeds.
ACTUAL -
JDK install fails
